HOUSTON -- Texans running back Arian Foster did not practice on Wednesday. He has not practiced since suffering a hamstring injury against the Kansas City Chiefs on October 20.

Foster said on Monday that he expected to practice at some point this week and work toward playing on Sunday against the Indianapolis Colts. Head coach Gary Kubiak said today that Foster's situation will be an end-of-the-week decision.

"Arian went out and stretched, did some stuff and did some walkthrough," Kubiak said. "And then he worked with the trainers. I think he's going to do everything he can to be there. But I think it'll be an end of the week decision, so we'll see. He did do some things, just not with the team once we got going."

The good news for Houston was that Ben Tate, Foster's backup, did return to practice.

Tate suffered cracked ribs against the Chiefs and played through the injury because he was the Texans' only remaining running back after they lost Foster that day. Kubiak said Tate went through all his normal reps for practice. We'll know what exactly that means when the injury report comes out this afternoon.

One way or another Houston will have three running backs against the Colts. At least one of those will be a player signed to the active roster this week: Deji Karim, Dennis Johnson or Ray Graham. They were all in training camp with the Texans and lost the roster spot to Cierre Wood.
